Lenovo Chromebook m 15

The Lenovo Chromebook m 15 is a big-screen ChromeOS laptop for home, school, and small-office work where screen space and a numeric keypad matter more than speed. It is the 15.3-inch sibling of the Lenovo Chromebook m 14, built on the same MediaTek Kompanio 540 but in a larger chassis with a full keyboard and number pad. Google lists its Auto Update Expiration date as June 2036, so it will keep getting ChromeOS updates for close to a decade. Buy the 8GB model: the 4GB configuration leaves little room for a modern browser with several tabs open.

A 15-inch plastic clamshell with a number pad

The Chromebook m 15 measures about 13.5 x 9.5 x 0.75 inches and weighs about 3.4 pounds, according to Lenovo’s PSREF specifications. The chassis is plastic in a Luna Grey finish, and Lenovo says it passed MIL-STD-810H military-standard testing. The larger footprint makes room for a six-row keyboard with a numeric keypad and a 4.7 x 3 inch buttonless touchpad. The keyboard has 1.3mm of key travel and no backlight. A physical shutter covers the 720p webcam, and the speakers are a pair of 2W drivers tuned with MaxxAudio.

The 15.3-inch IPS panel runs at 1920x1200 with a 16:10 aspect ratio, so it shows more lines of a document or spreadsheet than a 16:9 screen of the same width. Lenovo rates it at 400 nits with an anti-glare surface and a 1200:1 contrast ratio, but its color gamut is only 45% of NTSC. That is enough for documents, web pages, and video, but photos will look washed out next to a wide-gamut screen. The panel is non-touch and runs at 60Hz, and there is no pen support.

Ports are split across both sides. The left edge carries a USB-C port, a USB-A port, the headphone and microphone jack, and a Kensington Nano security slot. The right edge has the power button, a second USB-A port, a full-size HDMI 1.4b output, and a second USB-C port. All four USB ports run at 5Gbps, and both USB-C ports accept 45W to 65W USB Power Delivery and carry DisplayPort output, so you can charge from either side. Wireless is Wi-Fi 6E (2x2) with Bluetooth 5.3. There is no Ethernet port and no card reader.

Kompanio 540 performance and battery

The MediaTek Kompanio 540 is an eight-core Arm chip with two Cortex-A78 cores at 2.6GHz and six Cortex-A55 cores at 2.0GHz, paired with an Arm Mali-G57 MC2 GPU. It scores about 5,400 on PassMark’s CPU benchmark, which places it in the basic Chromebook tier, below the Intel Core and MediaTek Kompanio Ultra chips that Chromebook Plus models use. Lenovo claims 30 to 50% faster CPU and 75% better GPU performance than the older Kompanio 520, based on its own Geekbench 6 and GFXBench Manhattan 3.0 runs; those are vendor figures, not independent measurements. The chip suits web apps, Google Workspace, video calls, streaming, and Android apps. Large spreadsheets, many open tabs, and the Linux development environment push it hard.

Memory is LPDDR5X-6400, soldered to the board, and storage is UFS 2.2 flash, also soldered. UFS is faster than the eMMC storage that many budget Chromebooks still use. The 8GB model is the safer choice for a machine you plan to keep until 2036, because 4GB fills up quickly with a modern browser and Android apps running at the same time. With no card slot, extra storage comes from Google Drive or a USB drive.

Lenovo fits a 50Wh battery and rates it at up to 16 hours on Google’s power load test. That figure comes from a light, controlled workload, so expect less with the screen at full brightness or during long video calls. The included 65W USB-C adapter supports Lenovo’s Rapid Charge Pro, which Lenovo rates at 50% charge in 30 minutes.

Who should buy the Chromebook m 15

The Chromebook m 15 suits buyers who want a large ChromeOS laptop with a number pad for spreadsheets, budgets, or data entry, plus a long update window. The June 2036 AUE date means this model is still supported and will get security and feature updates for years. Full-size HDMI and four USB ports also make it easy to connect a monitor, mouse, and USB drive without a dock.

Skip it if you need a backlit keyboard, a touchscreen, or speed for heavy multitasking and Linux apps. For Chromebook Plus AI features and a faster chip at a similar screen size, compare the HP Chromebook Plus 15a or the Samsung Galaxy Chromebook Plus 15.
